CHILDS ADJUSTABLE CHAIR.

Specification of Letters Patent.

Patented June 14, 1910.

Application filed March 15, 1910. Serial No. 549,464.

To all whom it may concern:

Be it known that I, OSCAR G. NELSON, a subject of the King of Sweden,residing at Alliance, in the county of Stark and State of Ohio, haveinvented certain new and useful Improvements in Childrens AdjustableChairs, of which the following is a specification.

My invention relates to that class of chairs designed for the amusementand comfort of children, the object of the improvement being to controland adjust the back, foot rest and table going to make up the chair andother objects which will be readily apparent to those skilled in theart. I attain these objects by the construction illustrated in theaccompanying drawing, in which Figure l is a perspective view showingthe foot rest in its lowered position. Fig. 2 is a bottom or undersideview of the table and foot rest showing the table connected to the footrest. Fig. 3 is a view showing a. portion of the chair frame andillustrating the upper portion of the back in its normal position whenlooked as illustrated in Fig. 1. Fig. 1 is a horizontal section on line44, Fig. 3. Fig. 5 is a view showing a fragmental part of the chairframe and illustrating one of the catches for holding the guide bar,either in lowered or elevated posi tion. Fig. 6 is a vertical section ofthe chair seat showing a portion of the chair frame and illustrating thefoot rest in its lowered position. Fig. 7 is a side elevation showingparts in section and illustrating the back in an inclined position, alsoshowing the table connected and the foot rest extended. Fig. 8 is abottom or underside view of the seat, foot rest and connecting andretaining bars showing the foot rest in an extended position similar tothat shown in Fig. 7.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawing.

In the accompanying drawing, 1 represents the chair seat upon which maybe located the cushion 2. To the chair seat 1 is attached the chairframe, which consists of upright members, two of which constitute therear portion or members of the chair frame and are designated 3, theother two constitute the forward or front members of the chair frame andare designated by the numeral 4:. These four members are tied togetherby suitable tie bars or rods 5, which are connected to the upright chairmembers 3 and 1 in the usual manner, the lower portion of the chairframe proper being held by the chair seat 1. It will be understood thatthe chair frame within itself may be of the usual construction, exceptthat the frame is formed of sufficient length that a child can standupon the seat and be held in a standing position without danger offalling or the child may sit upon the seat. The object of providing achair upon which a child may stand is to provide means for permittingthe child to be amused by imparting an up and down movement to the chairframe, thereby producing a baby jumper, owing to the fact that the chairframe may be and preferably is suspended by means of the ropes -6 ortheir equivalents and the springs 7, which springs are connected in anyconvenient manner to the suspending ropes 6 and the springs connected attheir top or upper ends in any convenient manner to some overheadobject. The back 8 is hinged at its bottom or lower end to the seat 1 bymeans of the hinges 9, by which arrangement the back can be placed insubstantially a vertical position or at right angles to the seat orbrought into various inclinations as best illustrated in Fig. 7. For thepurpose of securely holding the back 8 in its vertical or uprightposition as illustrated in Fig. 1, the bars 10 are provided, which barsare secured to the rear members 3 by means of the clips 11, said barsbeing spaced from the rear frame members 3 for the purpose hereinafterdescribed. To the rear side of the back 8 and near its upper end isattached in any convenient and well known manner the housing 12, inwhich housing are located the beveled ended catch bars 13, which catchbars are normally held outward or extended by means of the springs 14.For the purpose of releasing the catch bars 18 their inner ends areprovided with the knobs 15, which knobs extend through the slot 16formed in the housing 12 so that they may be drawn toward each other,thereby releasing the catch bars 13 from the bars 8, at which time theback is free to be swung backward and into an inclined position.

For the purpose of limiting the backward movement of the back andholding the same in the desired inclined position, the links or arms 16are provided, which are pivotally connected to the back about midwaybetween top and bottom ends of the back 8. The links or arms 16 areprovided with the right angled portions 17, which right angled portionsare for the purpose of engagement with the notches 18 formed in the bars8. It will be understood that when the back is to be held in theposition shown in full lines Fig. 7 the links or arms 16 or the rightangled portions thereof engage the upper notches as illustrated in fulllines Fig. 7, and when the back is to be brought into variousadjustments the links or arms 16 are seated in the notches below theupper ones or they may be connected at the extreme bottom or angledportion 19.

It will be understood that when the chair back is brought from aninclined position to substantially a vertical position the beveled endsof the catch bar 13 will ride or strike against the bars 8, therebyforcing the catch bars inward or toward each other, but after the catchbars have fully passed the bars 8 they will be thrown outwardautomatically by the springs 14:, thereby locking the back in theposition illustrated in Fig. 7 or in substantially a vertical position.

To the bottom or underside of the base or seat 1 are attached the bars20 by means of the right angled flanges or ears 21, which bars areprovided with the cut out portions 22, which cut out portions are forthe purpose of producing what might be termed elongated slots oropenings as between the upper edges of the bars 20 and the bottom of theseat 1. To the bottom or seat 1 are also attached the plates 23 by meansof the fianges 24, which plates are provided with the rearward extendingfingers 25, said fingers being spaced from the bottom of the seat 1 asbest illustrated in Fig. 7 and are for the purpose hereinafterdescribed. To the bottom or underside of the seat 1 are secured thebrackets 26, to which brackets are pivotally attached the links 27 andto the bottom or lower ends of the links 27 are connected the foot restbars 28, which foot rest bars are provided with the elongated slots 29,through which elongated slots and through apertures 30 formed in thebottom or lower ends of the links 27 are passed the clamping bolts 31upon which clamping bolts are located the thumb nuts 32, thereby,pivotally and slidably connecting the foot rest bars 28 to the links 27.

To the forward ends of the foot rest bars 28 is pivotally connected thefoot rest 33 by means of suitable brackets 34. hen it is desired tobring the foot rest into the position shown in Fig. 1 or Fig. 6 thelinks 27 are permitted to assume suspended positions and when suspendedthey carry the foot rest bars 28 or in other words carry the forwardportions of the said foot rest bars. WVhen it is desired to bring thefoot rest into the position illustrated in Fig. 7 the nuts 32 areloosened after which the foot rest bars 28 and links 27 can be broughtinto substantially horizontal positions and parallel to each other,after which the foot rest bars can be moved longitudinally outward,thereby bringing the foot rest into the position shown in Fig. 7.

For the purpose of limiting the outward movement of the foot rest bars28 the cross rod 35 is provided, which cross rod is securely connectedto the foot rest bars 28 in any convenient and well known manner, bywhich arrangement the rear ends or portions of the foot rest bars aretied together and the forward ends also tied together by means of thebrackets 34, thereby holding the foot rest bars in proper spacedrelationship and parallel with reference to each other. As the foot restbars 28 are moved outward, the rest bars in proper spaced relationshipand the bottom of the chair 1,but when the cross rod 35 strikes the rearends of the plate 23 the outward movement of the foot rest bars will bestopped, but owing to the fact that the cross rod 35 comes above thefingers 25, there can be no rocking movement of the foot rest bars.

For the purpose of guiding the extreme rear ends of the foot rest bars28, they are each provided with the pintles 36, which are located atright angles to the foot rest bars 28 and moved back and forth in theslots 22 or more specifically in the cut out portions of the bars 20. ItWill be understood that the pintles 36 also provide a pivotal connectionfor the extreme rear ends for the foot rest bars 28, after said footrest bars have been moved backward and into the positions shown in Fig.6.

For the purpose of providing means for supporting a child while in astanding position and also arm rests, the sides 37 are pro vided, whichare fixed to the front and rear vertical members of the frame and forthe purpose of providing a front support for the child the bar 38 isprovided, which bar is adj ustably attached so that it can be broughtinto the position illustrated in Fig. 1 or into an elevated position. Insome instances it may be desirable to place the front bar 37 near thetop of the chair frame proper and for the purpose of providing means forholding the bar 38 in either an elevated or lowered position the frontmembers 4 are provided with suitable apertures 39 in which apertures areseated the spring actuated bolts 40. When it is desired to change theposition of the bar 38, the bolts to are pulled outward, therebywithdrawing the same from the apertures 39 after which the bar 38 can bemoved up or down, but when the bolts 40 register with the apertures 39,the bolts 40 will be automatically moved inward by means of the springs41 In some instances it may be desirable to provide what might be termeda table or tray for the use of the child, and therefore, the bottom orunderside of the bar 38 is provided with the brackets 41 and the table42 provided with the bars 43, which bars are extended so that theirextended portions can be inserted in the brackets 41 and the tablelocked in position by means of the catch 44, which catch is pivotallyattached to the bracket 45, which bracket is secured to the bottom orunderside of the table 42. The spring catch 44 is provided with thehooked end 46, which hooked end engages the pin 47, which pin issecurely attached to the bottom or underside of the bar 38.

For the purpose of preventing any accidental displacement of the catch44 the spring 49, is provided, which spring is so arranged that it willnormally hold the hooked end of the catch in proper engagement with thein 47 It will be un erstood that by the various adjustments of footrests and back with reference to the seat the chair can be brought intovarious positions and into such positlons that the chair can be used forvarious purposes; first, as a baby jumper; second, as a chair proper;and third, as a reclining chair or a swinging one.

Having fully described my invention, what I claim as new and desire tosecure by Let ters Patent, is

In a childs adjustable chair, the combination of a suspended frame, achair seat, brackets secured to the seat, links pivotally attached tothe brackets, foot rest bars provided with elongated slots, and meansfor slidably and pivotally connecting the links and foot rest barstogether, the foot rest pivotally connected to the forward ends of theslotted bars, parallel bars secured to the bottom or underside of theseat, said bars provided with cut out portions, plates secured to thebottom of the chair seat, said plates provided with rearward extendingfingers and a bar adapted to connect the foot rest bars together and tolimit the outward movement on said foot rest bars, and fingers adaptedto support said cross bars, substantially as and for the purposespecified.

In testimony that I claim the above, I have hereunto subscribed my namein the presence of two witnesses.

OSCAR G. NELSON.
